    I have PIC18F4550 board which has RS232 level interface built in (has only Tx and Rx pins). I also have bluetooth module which has configurations like D9 connector. I want to connect my bluetooth with my PIC18F4550 RS232 level. I will connect the Tx of bluetooh to Rx of PIC18F4550 RS232 level and Rx of bluetooth to Tx of PIC18F4550 RS232 level.

    My question is do I need to connect the CTS, DCD and DTR of the bluetooth together because I don't use these pins???
    Thank you
